HOT-WATER RADIATOR.

SPECIFICATION forming part of Letters Patent No. 560,257, dated May 19, 1896.

Application filed March 20, 1895. Serial No. 542,437. (No model.)

To all whom it may concern;

Be it known that we, AMOS M. CANON and WILLIAM G. MOREHEAD, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hot-Water Radiators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Our present invention has reference to a novel form of water-heater for house-warn ing purposes, and has for its object to provide a hot-water radiator in which the water is heated by means of a gas or other flame or flames, the construction of such radiator and the burner or burners connected therewith being simple and economical, and the radiator having the appearance of an ordinary steam or hot-water radiator. In our present form of construction the radiator-sections are filled with water, which is used over and over, the only loss being due to slight evaporation, which can be easily replaced.

A further object of our invention is to provide a radiator for a room, which can be connected with the ordinary gas -pipe in the building, or may be provided with any other suitable burner, such as that of an oil-lamp, to heat the water in the radiator and cause a circulation thereof through the radiator-sections, and when not required for further use, as in the summer, can be quickly disconnected and stored away until again wanted.

The invention consists in the novel combinations and arrangements of the radiator-sections and the heating chamber or reservoir, the radiator-sections being placed side by side and connected with each other, whereby a hot-water radiator is the result, which can be made up of any desirable number of radiating-sections to meet the requirements of the room to be heated.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a front view of our novel form of hot-water radiator. Fig. 2 is an end View of the same, and Fig. 3 is a longitudinal Vertical section of the radiator to more clearly illustrate the general arrangement and construction of the parts of the same. Fig. 4 is a horizontal section of the radiator, taken on line 00 in Fig. 3. Fig. 5 is a perspective View of the heating chamber or reservoir, a header and suitable pipe or conduit establishing a communication between said parts, and an arrangement of drop-tubes connected with the bottom of the said heating chamber or reservoir; and Fig. 6 is a bottom view of said reservoir and drop-tubes.

Similar letters of reference are employed in each of the above-described views to indicate corresponding parts.

In said drawings, a indicates the radiatorsections, which are made in the usual manner and comprise therein the tubular portions at and a ,with a centrally-arr. nged tube a which establishes a communication between said tubular portions a and' (L as will be understood from an inspection of Figs. 2, 3, and 4. The two end sections of the radiator are provided with ornamental legs a and when the radiator-sections are connected at the top by fittings 17, secured in the openings a, and at the bottom by fittings b, secured in the openings at, the parts will assume the appearance of an ordinary steamradiator, as will be clearly seen from an inspection of Fig. 1. In the two radiator-sections a in the center of the radiator the central tube a in each section is dispensed with and short tubes or conduits a are employed, each of which is provided with a fitting b in the top, which is secured in oppositelyplaced openings 0 in a suitable water-heat ing chamber or reservoir, as will be clearly seen from Fig. 3. In an opening in the top of said chamber or reservoir 0 we have secured a stand-pipe or conduit 0 which is tapped or otherwise secured in the bottom of a similar chamber or reservoir 0 called a header. This header 0 is provided with oppositely-arranged holes or openings 0 in which are secured suitable fittings b to establish communication with the hollow parts a of the radiator-sections a", and thence by means of the fittings b with the other radiator-sections. The lower side of said chamber or reservoir 0 is provided with any desirable number and suitably-placed holes or openings, in which are secured suitable droptubes cl, which are prefen bly surrounded by a cylindrical casing (1, as indicated in Fig. 3. The lower ends of said drop-tubes terminate directly above the burner c of a suitable gas-- stove e, fed from a perforated pipe e and arranged directly in the center of the radiator. In lieu of a gas-stove the burner of an oilstove may be employed, as will be clearly evident.

In order to give the radiator the general appearance of a steam-radiator the reservoir 0 is provided with suitable holding-lugs c and the header c is provided with correspondingly-arranged lugs c, and on these are secured the two blind radiator-sections a which serve no other purpose than to produce the general effect of a complete radiator and add to the beauty of the same. In the upper surface of the reservoir 0 is a perforation, in which we have secured a pipe 0 and which is in communication with an ornamental casing 0 provided in the top with a removable cap or plug 0 Said casing serves a double purpose: first, for filling the radiator with water, and, secondly, when the water is being heated it serves as an expansion-chambcr.

The end sections of the radiator are provided at the bottom with small faucets f and f and a faucet or cook f at the top to per mit the entrance of air into the radiator-sections and force the water therefrom when the cooks or faucets f and f are opened when it is desired to dispense with the further use of the radiator.

The gas-pipe 0 connected with the heater 6, is provided with a cook a, which can be turned on to permit the flow of gas into the burner 6.

hen the gas is lighted, the water in the drop-tubes cl becomes quickly heated and displaces the cold water in the chamber or reservoir c, in which the water also becomes quickly heated and rises in the tube or conduit 0 into the header c, from which the hot water passes in the direction of the arrows, as clearly indicated in Fig. 3, through the different radiator-sections,and finallyback through the short tubes or conduits a into the sides of the reservoir or chamber 0. At the same time that the dr0p-tubes cl are being heated and the water therein becomes displaced the conduits a which connect the lower ends of the radiator-sections with the water-heatin g chambers 0, will also receive heat from the heater, thereby causing a displacement of the cold water in said conduits, and hence a very rapid circulation of the water throughout the radiaton'sections. In this manner a complete circulation of the water in the radiator will be the result and the cold water therein, being displaced by the warmer water as it becomes heated in the chamber or reservoir 0,

several parts of the radiator will be the result. At the same time, the drop-tubes being con stantly filled with water, they cannot burn out, and should the radiator become too hot the flame in the stove or heater c can be regulated or can be extinguished and quickly relighted, when desired.

It will be evident that the radiator-sections as well as the number of burners in the stove can be increased to increase the heating capacity of the radiator. It will also be understood that any number of radiators may be connected in series, the water in all of them being heated from one stove or heater in one of the radiators and forming a complete circulation through the series of radiators, or each radiator in the series may be provided with a stove or heater directly connected therewith, as will be evident. Thus it will be seen that a cheap and serviceable hotqvater radiator is the result, which can be used to advantage in the winter and can be read ily detached from the gas connections in the room and stored away in the summer when there is no use for the radiator.

Of course it will be understood that we do not limit our invention to the exact arrangements and combinations of the parts as herein shown, as we are fully aware that they may be varied without departing from the scope of our invention.

In place of the gas-stove shown in connection with our novel form of hot-water radiator any suitable stove or heater having a gas or oil or other burner or burners may be used.

e are aware that it is not entirely new with us to combine with the water-sections of a radiator a heater to heat the water in said sections, whereby a circulation of the same is caused; but we are also aware that in' the constructions of radiators as heretofore made a large body of water has first to be displaced by the heat from the burner, thereby rendering the device impracticable for the reason that a free circulation of water cannot be brought about without maintaining a great consumption of gas to heat the large body of water. We have success fully overcome this difliculty, first, by the use of a comparatively large water-reservoir c, in which the water is heated, asmall standpipe 0 in which the water to be displaced is reduced to a minimum, and a large header 0 connected therewith, whereby a rapid circulation of the water in the several parts of the radiator is the result.

A second feature added to the above arrangement of the parts of the radiator, whereby a practical result is obtained, is the use, in connection with the water-reservoir c, of the drop-tubes d, in which the water is rap idly heated to displace the colder water in the other parts of the radiator.

Having thus described our invention, what we claim is-- 1. In ahot-water radiator, the combination,

with a series of radiator-sections, a waterheating chamber or reservoir situated above the lower ends of said radiator-sections, a heater beneath said reservoir, but practically above the lower ends of the radiator-sections, conduits providing communication between the lower ends of the radiator-sections and the reservoir, said conduits being so arranged as to receive heat from the heater, and a conduit providing communication between said reservoir and the upper ends of the radiatorsections, substantially as and for the purposes set forth.

2. In a hot-water radiater, the conibination, with a series of radiator-sections, a waterheating chamber or reservoir situated above the lower ends of the radiator-sections, a heater beneath said reservoir, but practically above the lower ends of the radiator-sections, conduit-s providing communication between the lower ends of the radiator-sections and the reservoir, said conduits being so arranged as to receive heat from the heater, a header above said reservoir, a tube or stand-pipe connecting said reservoir with said header, and connections providing communication between said header and the upper ends of the radiator-sections, substantially as and for the purposes set forth.

3. In a hot-water heater, the combination, with a series of radiator-sections, a waterheating chamber or reservoir situated above the lower ends of said radiator-sections, droptubes extending from said heating-chamber, a heater beneath said chamber and droptubes, but practically above the lower ends of the radiator-sections, conduits providing communication between the lower ends of the radiator-sections and the reservoir, said conduits being so arranged as to receive heat from the heater, and a conduit providing communication between said reservoir and the upper ends of the radiator-sections, substantially as and for the purposes set forth.
